TacFire MAR046 6-Position Buffer Tube Spring for AR-15 .223 Rem/5.56 NATO Black

The TacFire MAR046 is a 6-position buffer tube spring designed for AR-15 rifles chambered in .223 Remington / 5.56x45mm NATO. Engineered from piano wire-grade material, this replacement spring provides the firm, consistent recoil impulse your buffer assembly needs while noticeably reducing the audible "twang" that stock springs often produce during firing.

Measuring 10.875" long and finished in black, the MAR046 drops directly into a standard 6-position collapsible carbine buffer tube as an upgrade or direct replacement for worn or noisy factory springs. It is built to keep your AR-15 cycling smoothly with .223 Rem / 5.56 NATO setups, whether you are reassembling a carbine, swapping a mil-spec stock, or simply chasing a quieter action on the range.
